UNITED STATES JAMES E. ROAOHE, OF NEW YORK, N. Y.

IMPROVEMENT IN PlPE-TONGS.

Specification forming part of Letters Patent No. 125,221, dated April 2, 1872.

Specification describing a new and Improved Pipe-Tongs, invented by JAMES E. ROAGHE, of the city, county, and State of New York.

Figure 1 represents a sectional side view of my improved pipe-tongs. Fig. 2 is a transverse section of the same on the line C C, Fig. 1; and Fig. 3 is a transverse section on the line K K, Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to a new pipe-tongs or wrench of very simple construction, itsinovable jaw being arranged to slide, and actuated by a lever and spring, while the fixed jaw is adjustable by means of a screw, as hereinafter more fully described.

A in the drawing represents the main handle of my improved pipetongs, carrying at its outer end a hook-shaped block, B, in which the stationary jaw O of the pipe-wrench is held by a screw, a. D is the movable jaw of the wrench. It is fitted in a recess which is provided at the elbow-junction of handle A and block B. E is a lever, pivoted to the block B directly behind the jaw D, and having a projecting lug, b,that bears against the back of said jaw D. A spring, d, is concealed within a cavity, 0, of the block B, and bears against the face of a stud, f, which projects from the jaw D. The spring at has the tendency to crowd the jaw D against the lever E and to open the tongs, while the lever is used to bring the jaws together for clamping the pipe between them.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- The pipe-tongs composed of 'the block B, jaw O, screw a, movable jaw D, lever E, and spring 01, all combined to operate substantially as herein shown and described.
